Polyethylene wax(PE Wax) is used in hot-melt adhesives. Waxes in hot-melt adhesives are mainly used to adjust the viscosity, expand the wetting surface, increase the fluidity of the colloid, and adjust the solidification speed to achieve the purpose of fast bonding and firmness. If the viscosity of the melt glue is too large, it cannot or is not easy to flow, and it is difficult to penetrate into the signature, it cannot be firmly bonded.
Choosing different resins and waxes are also different. Low melting point paraffin wax, microcrystalline wax, high melting point Fischer-Tropsch wax, polyethylene wax. Polyethylene wax is used for hot melt adhesives based on its wide applicability. Polyethylene wax has good stability when used in hot melt adhesives. Compared with Mondan wax, polyethylene wax has better thermal stability. better. Therefore, it does not precipitate at high temperatures and will not have any impact on the appearance properties of the hot melt adhesive.
1. Hot melt adhesive for binding books and periodicals:
The packaging and sealing of food, beverages, instant noodles, cigarettes, beer, medicine, etc. are mostly done using hot melt adhesive through a carton sealing machine. The book and periodical binding industry has now abolished the old thread and staple binding and switched to hot-melt adhesive manufacturing technology, which not only improves the quality of binding, but more importantly, greatly speeds up the binding speed.
2. Pressure-sensitive hot melt adhesive:
Mainly used in maternal hygiene products, children’s diapers, hospital mattresses, incontinence products for the elderly, etc. Especially the latter, as my country’s population structure continues to age.
Polyethylene wax(PE Wax) has good stability when used in hot melt adhesives and has better thermal stability. Therefore, it does not precipitate at high temperatures and will not have any impact on the appearance properties of the hot melt adhesive. The hot melt adhesive produced by adding polyethylene wax has good cold resistance, heat resistance, acid, alkali and salt medium corrosion resistance and thermal stability, anti-slip, good fixation, high bonding strength, excellent temperature resistance, etc. Features.
